This place is a not-so-sober shit show come 2:00 a.m., which makes for excellent people-watching (if you can manage it in the dim lighting).

Portions are large, and they have everything from chicken and waffles to a Philly cheese-steak to a triple-decker PB&J. Not the healthiest options, but the convenient Sixth Avenue location makes for a perfect post-party stop — once you’ve been kicked out of every bar downtown. The food’s good but not great: Brian’s has been called “the upscale Denny’s.” The plus side? It never closes. Ever.

From old men sketching colored-pencil portraits to students flipping through textbooks to travelers browsing maps on laptops, you’re liable to encounter just about anybody at this 24-hour coffee shop with locations in Normal Heights (which hosts comedy on Tuesdays) and (more recently) University Heights.

The shop is spacious but has a cozy Edwardian vibe, no doubt in tribute to the notorious vampire for which it is named.

There’s live music most nights of the week, chiefly of the solo dude/chick-with-a-guitar variety. You’re not the only one up at 4:42 in the morning.
